When I startup, in dmesg I see : Local APIC disabled by bios. You can enable it with lapic Mapped apic to ffffd000 This means that the APIC is turned off by bios... so far so good... The only lines containing APIC in the .config of the kernel are :=20 CONFIG_X86_GOOD_APIC=3Dy CONFIG_X86_LOCAL_APIC=3Dy CONFIG_X86_IO_APIC=3Dy I have no idea where these options are in the make menuconfig menu. When = I manually change the y to a n, recompile the kernel and check again, the options are turned back to y. Am I missing something here ?=20 Any help is much appreciated !

This may be due to some kernel configuration options. According to your boot log, you enabled = the "processor" option in ACPI (CONFIG_ACPI_PROCESSOR), you should disable it (you will have to disable thermal zone too). As mentioned by Heikki, you may try disabling APIC too. If you get an error message on the console (you have run latency in text-mode for that), it will be of great help. --=20 Gilles Chanteperdrix.
